If you're still using Chrome for performance reasons:
- Firefox is now faster than Chrome out-of-the-box
- Firefox uses less memory than Chrome
- Contrary to Chrome, Firefox does not restrict Ad blockers, which will make your browsing experience much faster (and safer).

@bladecoder Is there a recent benchmark available between #firefox and #chrome ?

@slamp These stats from speedometer made the headlines lately:
https://treeherder.mozilla.org/perfherder/graphs?highlightAlerts=1&highlightChangelogData=1&highlightCommonAlerts=0&series=mozilla-central,3735773,1,13&series=mozilla-central,3412459,1,13&timerange=31536000&zoom=1658147734710,1689995242473,75.78916106949023,217.12296299642983
Benchmarks are still biased in general, Chrome is optimized to win some benchmarks which is not indicative of real-life performance.

@bladecoder @slamp I don't agree Firefox is faster, I use Firefox daily with adblockers etc and with the same set of extensions on Ungoogled chromium I find myself having a much smoother experience, on Fedora Linux.

I still use Firefox as my main browser because it's better packaged for Fedora.

I would like to use Librewolf as a Firefox alternative because Firefox has lots of undesirable things built in, but Librewolf has been stubborn with hardware acceleration so I still use Firefox.

@lle_bout @slamp I didn't know about ungoogled Chromium, I may give it a try as secondary browser. Makes me wonder how much of the Google stuff is still present in all those Chromium-based browsers.

@bladecoder @slamp Google or not, I think Chromium engine, v8 javascript engine, blink web engine, are more efficient than Firefox's, for good or bad reasons I don't know, but Google has so many engineers to work on this stuff, and performance, so..

Firefox on Android is also so bad in terms of load times, I often wait multiple seconds for pages to load. On Chromium-based it's much smoother, but also no extensions which is why I still use Firefox. I wish so much Firefox would be faster there.

@lle_bout @slamp Some components like v8 are definitely faster but I don't think it matters that much overall. Also Firefox has very good wasm performance

@bladecoder @slamp Realistically WASM is a very very small percentage of the web so it being fast is a good thing but practically what matters for smoother experience is HTML render performance and JavaScript execution latency performance

@bladecoder @slamp Also if I open too many tabs (60-80) without paying attention Firefox makes my 16GB laptop with 8GB compressed swap run out of memory on its own and crash to oblivion which is not a good experience. I don't know about ungoogled-chromium since I don't use ungoogled-chromium as much. I wish Fedora Linux or Linux in general had better OOM handling that actually work.
